This class is used to create html forms with validation. To use, in the head(html):
<script language="JavaScript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script language="JavaScript" src="validation.js"></script>
<script language="JavaScript">
var valid = new validate();
</script>
To setup the class:
<?php
include('formgeneration.php'); // load the class
$vf = new formgeneration('valid'); // The name of the javascript class is passed in
?>
Check the example index.php for an example of creating a child class that extends this class
To create the form(html):
<?php echo $vf->open_form()."\n"; ?>
To close the form:
<?php echo $vf->close_form()."\n"; ?>
To create a label:
<?php echo $vf->create_label('Name of object', 'Label')."\n"; ?>
To create a textbox:
<?php echo $vf->create_text('name', 'required')."\n"; ?>
Textarea:
<?php echo $vf->create_textarea('name', 'required', rows, columns)."\n"; ?>
Checkbox:
<?php echo $vf->create_Check('name')."\n"; ?>
Select List:
<?php
$values = array(
'' => 'Please Select',
'1' => 'Option 1',
'2' => 'Option 2',
'3' => 'Option 3',
);
echo $vf->create_select('name', 'required', $values)."\n";
?>
Radio button group:
<?php
$values = array(
'Milk' => 'Milk',
'Butter' => 'Butter',
'Cheese' => 'Cheese',
);
echo $vf->create_radio_group('name', 'required', $values)."\n";
?>
Post submit processng.
The set up is the same for the form. I use the following to redirect back to the input form on a validation error.
<?php
// post submit processing, normally done on thetarget page though one could useredirects
if (isset($_POST['submit'])) {
$error = $vf->validate();
if ($error != '') {
// do validation error proccessing
unset ($_POST['submit']); // we don't want this in the post data going back to the original form
?>
<form name="submision_form" id="submision_form" method="POST" action="/">
<?php echo $vf->savePostGet(); ?>
<input type="hidden" name="Message" value="<?php echo $error; ?>">
</form>
<script type="text/javascript">
$(document).ready(function() {
alert ('<?php echo $error; ?>');
$("#submision_form").submit();
});
</script>
<?php
exit; // redirect back to the original page
} else {
// Save the data or whatever
}
}
?>
